Amine BAND nnconni xre MACHINE.

Be itknown thatI, HARRYLANDsIEnEma citizen of thefUnited states, residing at Poplar Bluff, Missouri, have invented a new and useful Adding *aridl Recording Machine, of

which thefellowing isya specification.

Thisginvention relatesfto adding and recording machines of the cross carriage type, and it consists inf-the novel combination and arrangement of the. devices embodied therein as fully shown in the. accompanying drawings andfhereinafter described.

Another typeoit' machine to which this invention relates has been patented to Harry H. HelmicliinjLetters Patent of the United States No. 630,053, dated Aiigust 1, 1899,

and re-issued December 27, 1904, underNo.

12,296QAn advanced or improved type of this machine isydisclosed in anfapplication for acombined adding and writing machine filed by l-lnbertpHopkins January 24, 1902, having Serial Number 140,390, and eventuating in Patent No. 1,039,130, of September 24, 1.912. a y '1. a y

It is more specifically in combination with the l-Iopkinsmachine that this inventionis illustrated and described herein, though it will be obvious that it be embodied in any machine of the type referred to in which there is a movable pin carriage inwhich the numbers arefset up or represented through theaction. of keys or otherwise.

a One, object of the invention is to equip such a machine with a carriage of improved construction having number-representing devices, therein and guide-ways by which the number recording devices are properly guided and prevented i rominjurious vibra tions which sometimes result in ncorrect op erationofgthemachine. i

Another object is to pro tion witha carriage and the recording mechanism, tabulating devices -iinde r the control of the operator'whereby the carriagemaybe caused to move from its; idle or rest position to the position prev ously'o ccupiedby t adacent to the recordingdevices at 'asingle operation, the number-representing devices Me i c m ine-y I of Letters Patent. i a l 1 Patented July 6, 1915,

manipulation of the 'tabnlatingl mechanism whereby thecarrlage w ll'be causedto move automatically to proper; position for the opnismslto repeat saidnumber. a

A further object is to improveadding machines of the type which include a movable carrlage operation of which is necessary beeration of the recording or adding mocha fore theadding and recording mechanisms whereby, when the carriage is in one position, the 'tabulating mechanism may be operatedeffectively to release the escapement withotitsetting any of the tabulating stops, and when the carriage is in another position, ()peration of the tabulating mechanism will set one of the tabulating stops Without releasing the escapement.

Thereyare other objects to be attained by this invention than those specifically mentioned, all of which are intended to be made clear bythe following description, reference being made to the drawings.

@Figure l is'a side elevation of an adding and recording machine inv which my inventionhas been embodied, partsof the case being removed in order to disclose the con nections from the tabnlating key to the device controlled thereby. Fig. 2 is a longitudinal sectional view of the machine illustrating the automatic devices forrestoring the pinicarriag'e to idle; position after each numberhas been radded or recorded. Figs.

3 and 3 are specimens ofrecords performed :front of the carriage. Fig. 8isa rear b by such machine and illustrate the purpose v of the present invention. Fig. 4c is a vertical side elevation of a guide plate associated with the recording mechanism and the carriage. Fig.9 is a rear elevation of the carriage and the tabulating mechanism; Fig. 10 is a cross sectional view of the carriage.

Fig. 11 is a longitudinal sectionalview of the tabulating stop devices. Fig. 121s a cross sectional view of the tabulating device taken on the line 1212 of Fig. 11. Fig. 13 is a similar View taken onthe line 13-13 of Fig. 11. t r r I j i The keys 10 are arranged in convenient relation at the front of themachine, having levers 11 projecting rearwardly and ter-' minating in a row from front to rear. The said keys are ten in number, there being one for each of the ten digits or figures. The rear end of each lever, except the one for 9 is provided with a vertical extension or hammer 12, above which the movable carriage 13 operates. Said carriage is supported on rails 14 by means of anti-friction rollers 15. Said rails extend transversely and the carriage travels thereon in its movement from order to order when the number keys are operated' The carriage is provided with projections 16 extending into channels or grooves in therails 14 and serving as retainers to prevent removal of the carriage from the rails.

As usual, the carriage includes a series of.

rows of pins 17 Said pins are actuated downwardly by springs 18, Fig. 10, but may be moved vertically to registering position by operation of the number-keys, the extensions or hammers 12 engaging the lower ends of the pins when the said keys are operated, thereby moving the pins to registering position. Sliding latch plates 19 are arranged in proper relation with the rows of pins, whereby when any pin is raised it will be supported in its raised position until another pin in the same row isoperated, whereupon the latch plate will be moved to release the first pin and to engage with and support the second pin. In the upper portion of the carriage the upper ends of the pins extend into grooves or channels 20 within which the heels 21 of the racks 22 travel whenoperated to record numbers set up in the carriage. The racks 22 in the present instance, just as in the Hopkins patent referred to, swing from the shaft 23 and are cooperatively related to type carriers 24 swinging from the same shaft and adding mechanism B. to registeror add therein the numbers contained in the carriage when the racks are operated. The

mechanism for effecting intermittent connection of the adding mechanism with the racks is too well known at the present time ated in the other direction causing the adding mechanism to operate to add numbers in the'usual and well known way. As in said patent the carriage in the present instance is controlled by an escapement device which may be of any preferred type operable by the keys. In the present instance an escapement bar 25 rests upon the key levers 11 and isprovided with a pawl 26 arranged to escape upon a segment 27 attached to the vertical shaft 28. Said shaft 28 has an arm 29 secured at. its upper end and connected with the carriage bya pivoted link 30 whereby rotation of the shaft in either direction will cause corresponding movement of the carriage. An arm 31 is rigid with the shaft 28 and is actuated by a spring 32. i I

From the foregoing it will be seen tha operation of the key levers 11 will result in operation of the escapement permitting the spring 32 to move the carriage step by step across the machine to proper position with respect to the-racks 21 and the type carriers 2 4. The operation of the key levers also results in "setting the pins 17 to representthe number struck on the keys except as to the 9 key which, as previously stated, is without any pin-setting device.

The lever for the 9 key is provided with a standard 33, at theupper end of which a lever 34 is pivoted, said lever having one arm extending vertically and another arm extending under the adjacent rail 14. A spring 35 holds said lever in its idle position as shown in Fig. 4. Operation of the 9 key will cause the horizontal arm of the lever 34 to engage the under side of the adjacent rail 14 and Will cause the vertical arm of said lever to engage the front end of one of the plates 19 effectively to move said plate rearwardly and release any pin that may have been previously set in operative position. There is no pin 17 for the 9 key, the plate 36 being secured to the front side of the carriage in front of all of the rows of pins, said plate acting as an abutment for the heels 21v in operation of the racks and recording devices for adding and recordingx9s. The plates 19 move successively past the lever 34 in the same way that the pins 17 move successively over the key hammers 12. After each number is added or recorded the carriage is returned to its position as shown in Fig. 6,

the number which had been registered in the carriage and had been recorded or addthe pins are supported by the plates 19 until released by operation of other pins as previously mentioned;

i ed being yet retained in the carriage, since The machine of the Hopkins 1 patenttin cludes a rock shaft 60, (Fig. 2), whichyls rocked forwardly and rearwardly as nece sary c ompan m t of recor ng and adding operationsfg'An! arm 6l is support ed: on the shaft, and the springs 62 are arranged tor rock theshaft to l restore it to idle position afterieach" number has been recorded, in the well (understood manner. A link63 has its upper end pivotedupon a stationary support, and'itslower end pivoted to the; front end of a link 64. A rack 615onitherearjportion of saidflink meshes with a segment 66 loosely mounted on'the shaft 28 andihaving apinyGT extending downwardly therefrom, A pints extending upwardly from an arm i69-iwhich is rigidly attached to theshaft 28 is in the path of movement of the pin 67; When the carriage 13 moves from its idle positionathe arm 69moveswith the shaft 28 and carries thepin GS toward the pin 67, so that rearward movement of the link .64 will actuate the sesment fi di ng e r n' w the pinfiS effectivelyito rock the shaft 28 andrestore the carriage13 to its idle positionthrough the medium of the meshing segment 29 and rack 30. Aspring 70Iconnectsthe linkj63 with a stationary part'of the machine and yieldingly holds the link 16% in 'its fforwardposition The link 68- is providedwitha pin/71. The upper. end of the arm 61 supports a hook 72 which is provided with a all vertical arm. arranged to engage with a stationary part 73 when the shaft '60 isat rest, and thereby; holdsthe hook 72 in a plane below the pin 71. When the shaft is rockedforwardly, which is necessary in order to'record the number set up in the carriage 13, the hook 72 is carried forwardly andis raised by the tension of a spring 74 connecting a rearward'extension of the hook to a projection on the arm 61.

When initsforward position the hook 72 engages the pin? 1, so that when the shaft 60 is rocked to its idle position byflthe spring 62 the hook 72 Wlll actuate the links 62 and 6t,"and thereby rock the shaft 28 because ofjthe engagement of the pin 67 withthe pin68 as above explained, This return movement of the shaft60 after any number has been recorded or added in this manner automatically returns the carriage 13 to itsidle position. Asthe hookl72 appreaches its (idle position the upper arm thereof engages the stationary part 7 3 and thereby disengages said hookfromthe pin 71, after which the spring 7 0 retracts and movesforwardly the links 63 and 64:. These devices have; j their substantial counterpart in themaeh'ne of the Hopkins patent, and

fthe Dalton adding machine a which has i been manufactured t in @substantial conl formity with said patent.

:From th'e foregoing will that e the operation.

in order to repeat any number previously represented in the carriage after the carriage has returned to dle pos1t1on,1t will be necessary only to 7 move the v carriage to proper position with respect to the type carriers and racks,; and that nooperation of the pins in the carriagevvonld berequired.

This operation can be efiected either by operating the number keys again which will per Init the carriage to be moved-step byfstep,

a single operation to its proper position, i q a The sub ect-matter of the present invention includes suchtabulatmg mechan sm and comprisesa tabulating key 37 operatively supported n convenlent pos tion and having 5% or it may beeffectedby the .tabulating mech anism causing the carriage to be, movedat its stem extending through an opening in a the case of the machineiand resting upon one arm of therbell-crank lever 88, the op- 1 posite arm of which is connected by a link 39 witha lever 40 attached to a rock-shaft 41 supported by the side framespf thema chine at the rear of the carriage 13. A spring 42 encircles the, stem of the key each operation. to a slight extent longitudinally in its bearings, being actuated leftwardly by a spring a lever, 46 which is pivoted to the rail 14 at the rear. Thus in idle position of the carriage the tabulating key and mechanism are ineffective to operate the lever 46 and said lever maybe operated only after the carriagehas moved one or more spaces." The oppositeend of the shaft 41 supports a lever 47 extending over the tail of the pawl 26 when the shaft 41 is heldin idle position by the carriage; Operation of the tabulating key thereforelwill causeithe lever 47 torelease thepawl 26' from the segment 27 and permitjthe carriagetobe moved one or more spaces until stoppedby other devices than the pawl. The arrangement in this connectionis such that when the tabulating key is depressedthespring 43 ;will be ineffective to ;actuateathe shaft 41 until .saidkey is released, thereby retaining the leyer 4;? in engagement with thepaivl 26 throughout key 37 disengages the lever 47 from the pawl 26' and permits the spring 43 to actuate the shaft ll to the left with respectto the oper- Release of the tabulating 37 returning the same to idle position after a The shaft 4:1 is movable ator, th ereby moving the lever 47 beyond the awl 26 and placing the front end of the ever 40 overthe end of the lever 46.

Within the housing or frame 44 a row of pins 48 are mounted, said pins being arranged in alinement with the respective rows of pins 17. The pins 48 are arranged vertically being movable through holes in the upper and lower sides of the frame 44 and actuated to tl1611 lOWI' positions by encircling springs 49 mounted between ribs wardly to engage against the plate and operate it in opposition to its spring 52 until said rib 53 has passed above the plate, at

which time the plate will be moved under the rib andlatch the pin in its elevated position as shown in Figs. 11 and 13. It will be obvious also that when any one of these pins is'thussupported operation of any other pin willmove said last named pin to upper adjustments.

latched position above the plate 51 and will release the pin previously in such adjustment, permitting its spring to return it to idle position.

When the carriage moves leftwardly on operation of the number keys, the pins 48 are carried successively over one end of the lever 46 as may be seen by reference to Fig. 9. Also the leftward movement of the carriage causes the lever 40 to be placed in operative relationwith respectto the lever 46. Therefore, after any number whatever has been set within the carriage, the tabulating key may be operated effectively to cause the lever 46 to move one of the pins 48 to elevated position as shown in Fig. 11. The pin so moved in any case will be rearwardly from that row of pins 17 in which, or in advance of whichby operation of the 9 key, the last digit struck on the keys was registered. Operation of the recording mechanism will then cause the carriage to be returned to idle position as iswell understood, but the pins 17 which had been set to register the number and the pin 48 which had been elevated will all be retained in their As previously stated, the carriage may now be caused to move to operative position with respect to the racks 22 and their associated type carriers 24 by operation of the tabulating key which releases the escapement .and permits such movement. It is necessary, however, that some device be provided to stop the carriage at the proper position and to prevent it from being moved beyond the desired location. Iwill now describe-this'stopping device.

The shaft 41 has an arm 54 loosely mounted thereon and extending through a notch in a stationary plate'55 to which said arm 54 is connected'by a supporting spring 56 preventing said arm from dropping but permitting actuation thereof when desired. Theplate 55'prevents lateral movement of the arm 54 when the shaft 41 is moved by its spring'43 or by operation of the pin carriage. The sleeve to which the arm 54 is attached has a pin 57 extending laterally in front of a pin 58 rigid with the shaft 41 whereby rotation of the shaft by operation of the tabulating key will cause the arm 54 to swing downwardly into position tobe engaged bythe tabulating stop pin 48 which had previously been raised. Thus the'carriage will be stopped in position to present the previously registered number in proper relation .to the racks and their type-carriers so that said number may be repeated as often as desired without operation of the number keys. Release of the tabulating key at this time will permit the escapement pawl 26 to engage with the segment 27 and there'- by'hold the carriage from further movement.

digits in "lower ordersfr'om the numberalready therein. This is possible for the reason that. the arm 54 in idle position is at such altitude that'the pins 48 in their elevated position may pass thereunder. At any position of the carriage after any digit key has been struck, the tabulating key may be operated effectively to position the desired tabulating stop pin, provided the same has not been positioned at some other time, and to permit any other tabulating stop pin to be returned to idle position.

A tabulating mechanism of this'cha'racter in connection with these machines is especially valuable wherever multiplying or repeating :of numbers is required. By this mechanism any number registered in the carriage may be added or recorded as often as desired, and after the carriage has been returned to idle position and the adding mechanism cleared, the machinemay be put into immediate operation for repeating the same number further without the necessity of again setting said number in the carriage, and the manipulation of a single key is all that is required to cause the carriage to move to the required position irrespective of the number of digits inthe number to be added or recorded. The same key controls I the stop-setting mechanism of the tabulating devices and the escapement release,

I The arm 54 will also be raised asv soon as the tabulating key is released and thereby avoiding confusion and opportunity for error as would arise from the provision ofseparate keys for thesepiirpo'ses.
